Where: Queensland, Australia (26.6° S, 148.8° E)

• Paleocoordinates: 71.9° S, 135.4° E (Wright 2013)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Echinalosia ovalis brachiopod zone, Back Creek Group, Wuchiapingian (259.9 - 254.2 Ma)

• Presence of Echinalosia ovalis suggests an age within the E. ovalis zone, correlated with the middle part of APP5 palynomorph zone (Briggs, 1998). The APP5 zone was constrained as mid-Wuchiapingian through Changhsingian age by U-Pb dating in Laurie et al. (2016). However, overlying units in the Fort Cooper Coal Measures yield latest Wuchiapingian U-Pb ages (Phillips et al., 2018), constraining the upper Blenheim Fm to Wuchiapingian.
